Originally assigned to: @parkervcp on GitHub.

Current Behavior

When having a space or special character in a variable name (example APP_NAME or MAIL_FROM_NAME) in the .env file the docker container of panel doesn't start anymore, due to the way how the environment variables are loaded in the entrypoint.sh script.

Expected Behavior

The panel should start normally.

Steps to Reproduce

Have a space in an environment variable (for example APP_NAME) and start the panel, the panel will not start.

I think your env has a bad variable.... APP_URL is correct along with all the others with _

I had spaces in APP_NAME and a "-" in MAIL_FROM_NAME, removing any special characters fixed it for me... but anything after a space in a variable gets cut, for example APP_NAME="Pelican Panel" turns into just Pelican
the export $(grep -v '^#' .env | xargs) dislikes any special characters.
I changed it to . /var/www/html/.env which fixed it not accepting any special characters

Ohhh, I thought you meant the variable name itself had a space... My bad.

You can try using #2063 and see if that works for you.

I too agreed that sourcing the env with . /var/www/html/.env works but there is an issue with it potentially running shell commands if someone updates config values in the panel.
